Joangel-style Portfolio

Designed a sovereign ledger for an environment where exchange rates lie. Three FX columns per transaction, transfers as first-class records, atomic balance deltas with a fully audited log, and a cycle engine that turns recurring bills into linkable receivables. Shipped as 74 MCP tools + admin UI, used daily by the founder.

Started as a Saturday spike, grew into thousands of downloads and the first paid licenses inside a month. Built around a Surface system (pixel ↔ linear) so every primitive can switch aesthetics from one prop. The icon inspector + refinement skill turned visual QA into a repeatable loop.

A second-brain rendered for the room, not the laptop. Three modes (ambient, brief, focus), fluid clamp() scaling 390→1920, a multi-lane timeline (events + blocks + habits) with drag-edit, and an LLM-generated daily brief that learns from yesterday. Boot-instant via stale-fallback and a warm-pool of pre-primed agents.

Inherited a brittle monolith and shipped a calmer one: split admin and inspector workflows, added a typed event log, and rebuilt the registration flow to survive flaky connections in the field. Reduced a 14-step intake to 6 screens without losing a single regulated field.

Custom canvas effects, cinematic dark aesthetic, bilingual content, a generated CV PDF, and an AI-course funnel — all under 60kb of critical CSS. Built to be the calling card for client-facing work without smelling like a template.

Eleven Remotion compositions sharing one tokens file and one motion language. Render-script CLI, deterministic seeds, and a brand-pillar mapping so every clip ships on-brand without a designer in the loop. The CRT and CCTV effects are pure shaders, no After Effects.
